Features of concrete pump undercarriage structure

The bottom frame structure of used concrete line pumps is mainly composed of the rotary base and supporting leg. The rotary base bears the working weight and vibration of the arm frame. The supporting leg ensures the safety and stability of the Zoomlion pump truck at work. Because concrete braided pump truck is not installed with balance weight like the crane, when the horizontal extension of the braided pump truck is large, it will produce great overturning torque, which is mainly balanced by the counterforce of the supporting leg. Therefore, it is required that the supporting leg should have sufficient structure size and supporting area. At the same time, the base and supporting legs should have sufficient strength and fatigue resistance.

The base frame structure is mainly divided according to the extension support mode of the supporting leg: swing back and forth supporting leg, front and back extension legs and swing back supporting leg and front stretching back swinging leg.
